I came across this in the Omni telegram group, it seems that with EmblemVault you can create a crosschain wallet inside an erc721 token (NFT). It supports Omni blockchain. So you can trade MAID for some other token(other chain) via a NFT.
DesktopCommando, [23.09.21 19:44] At end of the month there will be a Omni chain swapping service for 2500+ crypto’s- without wrapping Paden Moss, [23.09.21 19:45] [In reply to DesktopCommando] That is excellent! Where may I learn more? DesktopCommando, [23.09.21 19:48] It’s a Emblemvault project - Omni layer is already on the app - we use NFTs to trade external blockchains, been using opensea which isn’t really good for an exchange - but our own is due at the end of the month DesktopCommando, [23.09.21 19:48] Means that you can swap Omni (whilst remaining on its own blockchain) with other chains Paden Moss, [23.09.21 19:55] So collections of assets can be represented by one NFT on opensea as ERC721: How do I transfer one asset from one collection in an NFT to another non-ERC721 chain? DesktopCommando, [23.09.21 20:03] Our ERC721 generate a blockchain address you send the amount to it and state what you want in return - the buyer fills theirs up with the requested crypto and you swap NFTs - 1 for 1 - claim the content and get the private keys to import onto the native currency wallets DesktopCommando, [23.09.21 20:03] https://youtu.be/OkUqJbx7S1s DesktopCommando, [23.09.21 20:04] This will help understand it DesktopCommando, [23.09.21 20:07] But means Omni layer and it’s tokens can trade with any others on the app Paden Moss, [23.09.21 20:17] Very interesting way to provide cross-chain liquidity by trading private keys in an NFT. DesktopCommando, [23.09.21 20:23] This way no need to provide Liquidity for a DEX - as you hold the funds in your NFT DesktopCommando, [23.09.21 20:23] Also no front running DesktopCommando, [23.09.21 20:23] If you want to swap 1 bitcoin for 1 Omni - you can DesktopCommando, [23.09.21 20:24] If they are daft enough DesktopCommando, [23.09.21 20:26] We are also listing every blockchain for free, so the pairings will get bigger
Some more info
a NFT with MAID
I am not really into this NFT stuff, but maybe other people find this interesting (as a MAID trading alternative)
